This program is third in the series of six Life Sciences Biology and Exploration of space video series. It provides a detailed account of the effects of gravity on the human circulatory system. Included is a discussion of how the loss of gravity-induced blood pressure gradients leads to medical problems associated with headward edema, reduced blood volume, and postflight orthostatic intolerance.

A preconditioned directional-implicit agglomeration algorithm is developed for solving two- and three-dimensional viscous flows on highly anisotropic unstructured meshes of mixed-element types. The multigrid smoother consists of a pre-conditioned point- or line-implicit solver which operates on lines constructed in the unstructured mesh using a weighted graph algorithm. Directional coarsening or agglomeration is achieved using a similar weighted graph algorithm. A tight coupling of the line...

Studies have shown that vegetation is directly sensitive to changes in the diffuse-to-global irradiance ratio and that increased percentage of diffuse irradiation can accelerate photosynthesis. Therefore, measurements of diffuse versus global irradiance could be useful for monitoring crop productivity and overall vegetative health as they relate to the total amount of particulates in the air that result from natural disasters or anthropogenic (manmade) causes. While the components of solar... Topics: COSMOLOGY, EVOLUTION (DEVELOPMENT), INTELLIGENCE, UNIVERSE, GROWTH, LIFE SCIENCES
The crucial subject of the shelf life of food products affects the manufacture, processing, distribution, sale and consumption of all foods. It is a hot topic that is on the mind of every 21st Century consumer and cannot be ignored. Following the clear and concise style of theBlackwell Food Industry Briefing Series, Shelf Lifeallows the reader to dip in and discover or re-discover how to manage shelf life of foods looking at definitions, regulations, responsibilities, and the important task of...

The Space Physics Analysis Network (SPAN) is a multi-mission, correlative data comparison network which links space and Earth science research and data analysis computers. It provides a common working environment for sharing computer resources, sharing computer peripherals, solving proprietary problems, and providing the potential for significant time and cost savings for correlative data analysis. This is one of a series of discipline-specific SPAN documents which are intended to complement... Topics: AEROSPACE MEDICINE, LIFE SCIENCES, NASA PROGRAMS, EXOBIOLOGY, SPACE LAW

The Space Shuttle Columbia's catastrophic failure has been attributed to a piece of external tank SOFI (Spray On Foam Insulation) striking the left wing of the orbiter causing significant damage to some of the reinforced carbon/carbon leading edge wing panels. Subsequently, several nondestructive testing (NDT) techniques have been considered for inspecting the external tank. One such method involves using millimeter waves which have been shown to easily penetrate through the foam and provide...

As the descriptive name suggests the book covers in detail how to grow vegetables in your kitchen garden. ...there are wide regions in the tropics where amateur vegetable gardening has its own specific features. To fill this gap we delivered courses of lectures between the years 1967 and 1986 on "Vegetable Cultivation and Production in the Tropics' to the students of the Department ofAgriculture at the P. Lumumba Peoples' Friendship University and published a textbook entitled... Topics: life sciences, agriculture, horticulture, vegetables, farming, kitchen garden, plants, soil

A common view is that the current global warming rate will continue or accelerate. But we argue that rapid warming in recent decades has been driven by non-CO2 greenhouse gases (GHGs), such as CFCs, CH4 and N2O, not by the products of fossil fuel burning, CO2 and aerosols, whose positive and negative climate forcings are partially offsetting. The growth rate of non-CO2 GHGs has declined in the past decade. If sources of CH4 and O3 precursors were reduced in the future, the change of climate...

The advent of powerful graphics workstations and computers has led to the advancement of scientific knowledge through three-dimensional (3-D) reconstruction and imaging of biological cells and tissues. The Biocomputation Center at NASA Ames Research Center pioneered the effort to produce an entirely computerized method for reconstruction of objects from serial sections studied in a transmission electron microscope (TEM). The software developed, ROSS (Reconstruction of Serial Sections), is now... Topics: ANIMALS, LIFE SCIENCES, PHYSIOLOGICAL EFFECTS, PHYSIOLOGY, BIOTELEMETRY, AEROSPACE ENGINEERING,...
A number of numerical solution technologies were developed for advanced analysis capabilities involving the finite element method in advanced constitutive modeling and structural analysis for improved and rational designs of aerospace propulsive systems. These technologies were incorporated into several advanced viscoplastic models and were applied to a wide spectrum of structural engineering problems involving extremes of thermal/mechanical loading. Results of the research performed under the... Topics: EDUCATION, SCHOOLS, LIFE SCIENCES, NASA PROGRAMS, INFORMATION DISSEMINATION, INSTRUCTORS, STUDENTS,...
Concerning ground-based space physiological research, the choice of analog must carefully match the system of interest. For spaceflight-associated immune dysregulation (SAID), Antarctica winter-over has emerged as potentially the best terrestrial analog. The prolonged mission durations, extreme/dangerous environment, station-based lifestyle, isolation from outside world, disrupted circadian rhythms, and other psychological aspects make this analog extremely high fidelity for exploration-class...

This study assesses the use of capacitor powered Hall thrusters for drag makeup of a sample LEO spacecraft. Charged by solar array power, the capacitors provide high voltage power directly to the Hall thrusters, alleviating the need for a costly power processing unit. Capacitor driven Hall thruster performance is compared to a baseline state-of-art hydrazine monopropellant system as well as Hall thrusters driven through a power processing unit directly connected to solar array power or a...
